The molecule of an element can be represented using a chemical formula by stating the symbol of the single type of atom present in it, along with its count. For instance, the molecule of chlorine (Cl) has two atoms. Therefore, it is represented by the chemical formula Cl2. The molecule ...

What type of chemical element is chlorine? Which chemical element has the symbol Sn? What element has atomic number 4? What element has the atomic number 74? What element has the atomic number 1? What element has the atomic number 7?
Each of the chemical elements is designated by a simple symbol, for example, carbon, C, copper, Cu, chlorine, Cl, sodium, Na. When a compound occurs between elements the compound can be symbolised by a formula indicating the elemental constituents as for common salt, sodium chloride, NaCl....
(fluorine, chlorine, bromine and iodine) nearly always form ions that have gained a single electron. Sulfur and oxygen can form ions with a -2 charge. Elements in the middle of the table — the so-called transition metals — can lose a variable number of electrons. The number of ...
